VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1929-1932 6 volt generator

I disassembeled my 6 volt generator. Everything looks fine except for the paper coverind the windings. I worked fine prior to disassembly, what should i recover the windings with,
My car is a 30 standard coupe

There is a special field coil insulating wrapping cloth that is used. Your local starter/alternator shop may have some in stock but many shops don't take the time to rewrap field coils because it is more cost effective to install new field coils instead.

When the field coils are rewrapped, the old material must be removed first.

Good morning, can i wrap the field coils with anything other than the paper

The field coils can be wrapped with either the special field coil wrapping cloth or the wrapping paper. The wrapping paper has been discontinued however, but it still might be in stock at some of the starter shops. The wrapping cloth is what is now used. Your other choice is to purchase new field coils which are still available for that generator. DON'T USE ELECTRICAL TAPE TO WRAP THE FIELD COILS!

When installing the field coils it takes a special field coil vise to tighten down the pole shoe screws to suck in the field coils tight against the generator case otherwise the armature will drag on the pole shoes. Also, if you put on the field coil wrapping too thick the same problem will occur.

You might be better off to take your generator to a local starter shop and let them do the job for you.

There is a product called Glyptal, that has been used in industrial use electric motors and generators, seems to work fine. I have come across it for the past 30 years just DO NOT BRUSH IT ON THE COILS WHILE ON THE POLE SHOES! I had found that once the stuff hardens you will have a real tough time getting the screws out of the pole shoes, if you ever can without braking them.
I am sure JYD will agree that the most common reason for generator failure all goes back to the bearing(s) and bushing failing and allowing for the armature to "wobble" and everything goes down hill from there

Right! Typically with generators it is not unusual for the armature to be dragging on the pole shoes due to a bad generator bearing and end frame bushing. And, almost always the armature comm. is out of round. Also, most of the time the field coil wrappings are deteriorated as well and the field coils either need to be stripped and rewrapped or replaced. Of course, it goes without saying that the brushes should be replaced too.
